Great story! I'm glad you finally got another betta :) Sorry about your ankle. I've been on crutches for a month before so I feel your pain, it's so annoying!

As for the parasites, maybe a picture? I've found Quick cure to work well with ick, and it says it can be used with other external parasites as well, however I don't know what your fish has so I can't recommend it. I also have Clout on hand although I've never had to use it.
